I would like to get your opinion on running a publisher advertiser network website like google adsense and adwords for a local community. There are some scripts avaialable that helps run a network portal instantaneously, like Inout Adserver from www.inoutscripts.com What do you think running such a service for my state or small country will be a viable business idea? Or will one won't be able to win the competition of Google?

I am inviting your suggestion on this small business idea. It is small as the targeted market is small, but anytime one can expand the target also. Let me know your ideas.
